You're free not to believe me, but I do shipped 3 commercial games (links in profile). I know that what would usually take to build 2-3 months of developer time can now be built in a week.

PS: I might eventually post here about rapid game prototyping with LLM.

If you actually have some credibility feel free to reach me via Linkedin or non-anonymous email and I'd happily share my experience or the code.
